I made the following module with a custom entity in it. 
This is all working fine, but now i want to make a entity reference field in some content type to this custom entity.
For this i made the ConfigurationSelection.php file which looks like this :
<?php
namespace Drupal\sg_configuration_rule\Plugin\EntityReferenceSelection;
use Drupal\Core\Entity\Plugin\EntityReferenceSelection\DefaultSelection;
/**
* Provides specific access control for the comment entity type.
*
* @EntityReferenceSelection(
* id = "default:sg_configuration_selection",
* label = @Translation("Configuration Selections selection"),
* entity_types = {"configuration_rule"},
* group = "default",
* weight = 1
* )
*/
class ConfigurationSelection extends DefaultSelection {
/**
* {@inheritdoc}
*/
protected function buildEntityQuery($match = NULL, $match_operator = 'CONTAINS') {
$query = parent::buildEntityQuery($match, $match_operator);
return $query;
}
/**
* {@inheritdoc}
*/
public function createNewEntity($entity_type_id, $bundle, $label, $uid) {
$rule = parent::createNewEntity($entity_type_id, $bundle, $label, $uid);
return $rule;
}
/**
* {@inheritdoc}
*/
public function validateReferenceableNewEntities(array $entities) {
$entities = parent::validateReferenceableNewEntities($entities);
return $entities;
}
}
This custom entity is not found when want to select it when adding a reference field:
My entity itself looks like this:
<?php
namespace Drupal\sg_configuration_rule\Entity;
use Drupal\Core\Entity\ContentEntityBase;
use Drupal\Core\Entity\EntityChangedTrait;
use Drupal\Core\Entity\EntityStorageInterface;
